### Test Path Fixes After HTTP Module Refactoring

**Problem Description:**
After moving the HTTP Gateway and Routes modules from `src/http/` to `src/sms/`, the import paths in test files became invalid, causing `cargo test` compilation failures.

**Error Messages:**
```
error[E0433]: failed to resolve: could not find `http` in `spear_next`
error[E0432]: unresolved import `spear_next::http`
```

**Affected Test Files:**
- `tests/http_integration_tests.rs` - HTTP integration tests
- `tests/task_integration_tests.rs` - Task integration tests

**Fix Details:**

1. **Import Path Updates**
   ```rust
   // Before Fix
   use spear_next::http::create_gateway_router;
   use spear_next::http::gateway::GatewayState;
   
   // After Fix
   use spear_next::sms::routes::create_routes;
   use spear_next::sms::gateway::GatewayState;
   ```

2. **Function Call Updates**
   ```rust
   // Before Fix
   let app = create_gateway_router(state);
   
   // After Fix
   let app = create_routes(state);
   ```

**Fix Results:**
- HTTP Integration Tests: All 6 tests passed
- Task Integration Tests: All 5 tests passed
- Overall Results: `test result: ok. 26 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out`

## Fixed Issues

### 1. ObjectRef Integration Test Query Parameter Issues

**Problem Description:**
- `test_objectref_list_with_filters` test failed with 404 error
- Test used direct URL concatenation for query parameters: `/api/v1/objects?limit=1`

**Root Cause:**
- `axum-test` library requires using `add_query_param` method to properly handle query parameters
- Direct URL concatenation of query parameters causes route matching failures

**Solution:**
```rust
// Before fix
let response = server.get("/api/v1/objects?limit=1").await;

// After fix
let response = server
    .get("/api/v1/objects")
    .add_query_param("limit", "1")
    .await;
```

**Fixed Test Cases:**
- All GET requests with query parameters now use `add_query_param` method

### 2. ObjectRef Integration Test JSON Data Format Issues

**Problem Description:**
- `test_objectref_sequential_operations` test failed with 422 (Unprocessable Entity) error
- JSON data format sent by test didn't match API handler expectations

**Root Cause:**
- `PutObjectParams` struct expects specific field formats:
  - `name: String` (required field)
  - `data: Option<Vec<u8>>` (binary data)
  - `tags: Option<Vec<String>>` (string array)
- Test sent incorrect data format:
  - Missing required `name` field
  - `data` field sent as base64 string instead of binary data
  - `tags` field sent as object instead of string array

**Solution:**
```rust
// Before fix
let object_data = json!({
    "data": format!("ZGF0YS0{}", i), // base64 string
    "metadata": {
        "content_type": "text/plain",
        "size": 10
    },
    "tags": {
        "index": i.to_string(),
        "test": "sequential"
    }
});

// After fix
let data_string = format!("data-{}", i);
let data_bytes = data_string.as_bytes().to_vec();

let mut metadata = std::collections::HashMap::new();
metadata.insert("content_type".to_string(), "text/plain".to_string());
metadata.insert("size".to_string(), "10".to_string());

let tags = vec![
    format!("index:{}", i),
    "test:sequential".to_string()
];

let object_data = json!({
    "name": format!("test-object-{}", i),
    "data": data_bytes,
    "object_type": "bytes",
    "metadata": metadata,
    "tags": tags
});
```

### 3. Reference Operation Test JSON Request Body Issues

**Problem Description:**
- Reference operation tests failed with 415 (Unsupported Media Type) error
- `add_ref` and `pin_object` operations didn't send JSON request body

**Root Cause:**
- `add_ref` and `pin_object` handlers expect JSON data: `Json(params): Json<AddRefParams>`
- Tests only sent empty POST requests without JSON data

**Solution:**
```rust
// Before fix
let response = server
    .post(&format!("/api/v1/objects/{}/ref", object_id))
    .await;

// After fix
let add_ref_data = json!({
    "reason": "test reference"
});
let response = server
    .post(&format!("/api/v1/objects/{}/ref", object_id))
    .json(&add_ref_data)
    .await;
```

## Fixed Test Files

### `/tests/objectref_integration_tests.rs`

**Fixed Test Cases:**
1. `test_objectref_list_with_filters` - Query parameter fix
2. `test_objectref_sequential_operations` - JSON data format and reference operation fixes

**Fix Details:**
- All query parameters use `add_query_param` method
- Object creation data format conforms to `PutObjectParams` struct
- Reference operations include required JSON request body

## Technical Points

### 1. Correct Usage of axum-test Library

```rust
// Correct way to pass query parameters
server.get("/api/v1/objects")
    .add_query_param("limit", "10")
    .add_query_param("offset", "0")
    .await;

// Correct way to send JSON data
server.post("/api/v1/objects")
    .json(&object_data)
    .await;
```

### 2. API Data Structure Matching

Ensure test data exactly matches the data structure expected by API handlers:
- Field names must be consistent
- Data types must match
- Required fields cannot be missing

### 3. HTTP Status Code Understanding

- **404 Not Found**: Route matching failure, usually URL or query parameter issues
- **415 Unsupported Media Type**: Request Content-Type not supported, usually missing JSON data
- **422 Unprocessable Entity**: Request format correct but data cannot be processed, usually data structure issues

## Test Results

After fixes, all integration tests pass successfully:

```
Running tests/objectref_integration_tests.rs
running 7 tests
test test_objectref_content_types ... ok
test test_objectref_error_handling ... ok
test test_objectref_lifecycle ... ok
test test_objectref_list_with_filters ... ok
test test_objectref_pin_unpin_operations ... ok
test test_objectref_reference_counting ... ok
test test_objectref_sequential_operations ... ok

test result: ok. 7 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out
```

## 4. Test Logging Optimization

### Problem Description
Test output contained numerous HTTP/2 protocol debug logs, such as `debug h2::codec::framed_read:`, which were not helpful for test result analysis and added noise to the output.

### Solution
Added unified logging initialization functions for all integration tests to filter out noisy protocol-layer debug logs.

#### Before Fix
```rust
// In objectref_integration_tests.rs
tracing_subscriber::fmt().with_env_filter("debug").try_init()

// In task_integration_tests.rs
// No logging initialization
```

#### After Fix
```rust
// Added unified logging initialization function in both test files
pub fn init_test_tracing() {
    INIT.call_once(|| {
        // Filter out noisy HTTP/2 debug logs
        let _ = tracing_subscriber::fmt()
            .with_env_filter("spear_next=info,h2=warn,hyper=warn,tower=warn,axum=warn")
            .try_init();
    });
}

// Called at the beginning of each test function
#[tokio::test]
async fn test_objectref_lifecycle() {
    // Initialize tracing for debugging
    objectref_test_utils::init_test_tracing();
    // ...
}
```

### Technical Points
- Used `std::sync::Once` to ensure logging is initialized only once
- Set appropriate log levels: application level at `warn`, protocol layer at `warn`
- Unified logging configuration for easier maintenance and debugging
- Further optimization: Adjusted application log level from `info` to `warn`, completely eliminating runtime log output

## Lessons Learned

1. **Carefully read API handler data structure definitions** to ensure correct test data format
2. **Understand correct usage of testing frameworks**, especially query parameter and JSON data passing
3. **Quickly locate problem types based on HTTP status codes** to improve debugging efficiency
4. **Maintain test data consistency** by using unified data generation functions

## 5. Compilation Warning Fixes

### Duplicate ErrorResponse Definition Issue

**Problem Description:**
- Both `task.rs` and `objectref.rs` modules defined the same `ErrorResponse` struct
- This caused ambiguous re-export warnings

**Solution:**
1. Created a common `ErrorResponse` type in the `common.rs` module
2. Updated `task.rs` and `objectref.rs` to use the common type
3. Updated module re-export configuration

**Modified Files:**
- `src/http/handlers/common.rs` (new)
- `src/http/handlers/mod.rs`
- `src/http/handlers/task.rs`
- `src/http/handlers/objectref.rs`

### Unused Import Warning Fixes

**Problem Description:**
- Multiple files contained unused imports causing compilation warnings
- Including unused `Mutex`, routing, CORS, macro imports, etc.

**Solution:**
1. Removed unused `Mutex` import from `task.rs`
2. Removed unused `axum::routing` and `tower_http::cors` imports from `gateway.rs`
3. Removed unused `tower_http::cors` import from `routes.rs`
4. Removed unused KV store imports from `node.rs` and `resource.rs`
5. Put macro imports in `kv.rs` under conditional compilation blocks
6. Fixed `json!` macro usage in `objectref.rs`
7. Added `#[allow(dead_code)]` annotation for `started_at` field in `task.rs`

**Modified Files:**
- `src/services/task.rs`
- `src/http/gateway.rs`
- `src/http/routes.rs`
- `src/services/node.rs`
- `src/services/resource.rs`
- `src/storage/kv.rs`
- `src/http/handlers/objectref.rs`

**Result:**
- All compilation warnings cleared
- Cleaner code with no unused imports
- Proper handling of conditional compilation macro imports

## Summary

This fix resolved multiple critical issues in integration tests, ensuring test stability and reliability. Key achievements include:

1. **Comprehensive ObjectRef Integration Test Fixes**: Resolved query parameter, JSON data format, and reference operation issues
2. **Test Logging Optimization**: Filtered out noisy protocol-layer debug logs, improving test output readability
